A joint police and health and safety investigation is under way after a man died in a farm accident on 20 October.
Emergency services were called to Church Farm, Philips Lane, Darrington, West Yorkshire, to reports of a man having suffered a serious head injury.
The 68-year-old was airlifted to hospital, but he later died from his injuries.
A spokeswoman for West Yorkshire Police confirmed: “A 68-year-old man was taken by air ambulance to Leeds General Infirmary with a serious head injury.
“He sadly passed away from his injuries.”
The Health and Safety Executive (HSE) said it had been informed of the fatality and was working with police to establish what happened.
“HSE is aware of the incident and is assisting the police, who have primacy,” said an HSE spokesman.
Worker cut free
Elsewhere in the county, firefighters were called in to action on Saturday night (28 October) to cut a man free from farm machinery in Staxton, North Yorkshire.
Fire crews used hydraulic cutting equipment to release the man from the machinery. He was then taken to Hull Royal Infirmary by air ambulance.
His injuries, although serious, were not thought to be life threatening.
